And I in turn think you (or perhaps someone else)are making an error
in your use of the term "UTC".

time-utc->date seems to think that a leap second occurs at a different
time in each time zone:
scheme@(guile-user)> (use-modules (srfi srfi-19))
scheme@(guile-user)> (define (tdate d) (write (list (date->string d "~4")
(date->string (time-utc->date (date->time-utc d) 3600) "~4"))) (newline))
